Recommended deployment procedure
Plugline Inflatable Pipe Stoppers are used for sealing, blocking and pressure testing pipework. Follow the procedure below for safe installation and removal.
Verify each stopper for surface defects. Confirm reference matches purchase order. Pre-test in a clean environment to nominal 0.5 bar.
Insert deflated. Place at least two pipe-diameters inside the bore. Secure the connector hose to the inflation valve.
Inflate to nominal pressure indicated on the datasheet. Hold for 60 seconds and verify seal under audible test.
Perform line test per EN 1610 or local code. Record drop, hold time, ambient temperature.
Deflate fully before withdrawal. Inspect for damage. Stopper may be reused for up to 200 cycles under nominal conditions.
